John Kerry Warns Stubborn Congress Not To Threaten Negotiating Power

According to John Kerry, the Congress now holds within it's grasp the credibility of American diplomatic negotiating.
The Secretary of State warned that should Congress not pass the deal stricken with Iran to curb their nuclear enrichment program, the future of diplomatic credibility will be weakened.
Kerry's concern is that other nations will perceive the United States as having 536 top diplomats, the secretary running the State Department and every single member of Congress.
He added that they may feel confusion as to who they are negotiating with.
The secretary of state was adamant that the deal was the best available and was no longer up for negotiation.
Kerry said, "if Congress rejects this, Iran goes back to its enrichment...the Ayatollah will not come back to the table...the sanctions regime completely falls apart."
